For over fifteen years, Spider 9 axles have powered more top podium finishes than any other axle on the planet. From the early days of 26 spline Suzuki Samurai shafts to the latest gun-drilled 45 spline Ultra4 racing axles, we take pride in making the industry’s best axle shaft for any off-road application.

We are proud to release these latest H1 Portal 32 spline axle shafts with that same spirit in mind, now sized for 1480 u-joints. This one-piece billet axle shaft is manufactured from our race-proven E4340 chromoly material. Every cross-section is optimized to provide the highest strength in a webbed design capable of a massive 50 degrees of steering. Coupled with our precision in-house turning, milling, and splining operations, this stub shaft will perfectly fit an H1 Portal box every time.

There are many things to be excited about when diving into a racing series. My top two are watching for the fastest drivers and seeing the latest and greatest technology. Sometimes, both of these things go to one team, as is the case with Loren Healy and his latest 4400 Ford Bronco inspired Ultra4 build. There’s a lot to unpack in Loren’s latest creation, and it just so happens that Ali Mansour of Drivingline.com recently spent the time dissecting it all. We hope you enjoy the details of this build as much as we do; read the full writeup over at Drivingline.com.
